I think the above listed gambling site are reputable gambling site which you can trust, they have been in existence for long time and they don't have any record of scam accusation.
Also make sure you avoid 1xbet and 1xbit, they are scam gambling site and they can't be trusted, am sure you will have seen different scam accusation about them, so make sure you keep off or you might endup losing your money there. All the forum members marketing for them are just doing it for their own selfish interests.
